-LRB- CNN -RRB- -- Thousands of travelers have been left in the lurch around the world after the carrier Air Australia went into administration and grounded its fleet Friday .

`` It currently appears that there are no funds available to meet operational expenses so flights will be suspended immediately , '' the company said in joint statement Friday with its newly appointed administrators , KordaMentha .

About 4,000 passengers in total have been left stranded in Hawaii , Thailand , Indonesia and Australia as a result of the suspension , said Michael Smith , a spokesman for KordaMentha .

`` It also appears highly unlikely there will be any flights in the short to medium term , '' the airline 's statement said , advising passengers to make alternative arrangements .

The airline had sold about 100,000 tickets for future flights , Smith said . With no indication from Air Australia when it might resume operations , those tickets could end up worthless .

Some customers may be entitled to refunds , the airline said , depending on how they bought their tickets . But it added that customers without the relevant insurance who paid in cash are unlikely to be eligible for refunds .

`` Apparently , the straw that broke camel 's back was inability to pay for airline fuel , '' said Michael Ilyine , an accountant from Geelong , Australia .

Ilyine and his wife were on their honeymoon in Thailand when they were left stuck at the airport in Phuket , he said , after their Air Australia flight was grounded with their baggage in the hold .
